FURNACE AND PROCESS FOR SYNGAS PRODUCTION

A furnace (1) for the production of syngas comprising: • - a radiant zone (2), • - a convective zone (3), • - a first (4) and at least a second series of pipes (5) through which at least two segregated process gas flows (A) and (B) respectively pass: wherein: • · the first process flow (A) enters said furnace (1) from the convective zone (2) and, passing through said first series of pipes (4), leaves said furnace of the radiant zone (3), or in alternative said first process flow enters said furnace (1) through the radiant zone (2) and, passing through the first series of pipes (4), leaves said furnace through the radiant zone (2); • · the second process flow, intended for the treatment of acid gases, enters said furnace (1) from the convective zone (2) passing through said second series of pipes (5) and leaves said furnace (1) through the convective zone (2), • · said second series of pipes (5) is made of material resistant to acid gases. A process for the production of syngas in such a furnace comprising the steam reforming of methane in the first series of pipes and the catalytic decomposition of H2S in the second series of pipes.
